🔍 Key Concepts

• Study how many talking circuits are shown between all four stations – are they separate or shared? • Notice how each station is labeled "Rings on #4, #6, #7, #9" – what does this say about the ringing circuit? • Recall the difference between common (party-line) circuits and selective circuits in sound-powered phones.

💭 Think About

• Look at the bundle of wires running horizontally between all stations. Does this layout look like one shared line or multiple isolated lines for talking? • Focus on the station labels and the selector positions with numbers 1–11. Why would each station have a unique ring number if the ringing were common? • If everyone can hear conversation once connected, but only certain stations ring when called, which parts of the system must be common and which must be selective?

✅ Before You Answer

• Verify whether there is one talk bus shared by all four stations or separate talk lines per station. • Confirm that each station has a distinct ring number (e.g., "Rings on #4, #6, #7, #9") tied to the selector switch. • Match that observation to the answer choice whose wording pairs common vs selective correctly for talk and ringing.
